In an email to fans, Louis C.K. called Trump an "insane bigot" and "dangerous." He wrote:

Please stop it with voting for Trump. It was funny for a little while. But the guy is Hitler. And by that I mean that we are being Germany in the 30s. Do you think they saw the sh-- coming? Hitler was just some hilarious and refreshing dude with a weird comb over who would say anything at all. ... If you are a true conservative. Don’t vote for Trump. He is not one of you. He is one of him.

He also clarified that the email didn't mean he was endorsing Hillary Clinton or Bernie Sanders either: "I like them both, but frankly I wish the next president was a conservative only because we had Obama for eight years and we need balance."
